What kinds of hot air guns can be divided into?
Normal type Heavy Duty Hot Air Gun
This kind of hot air gun is mainly characterized by unstable temperature, high and low, and unstable air volume. The scale of this air gun only adjusts its power, so the temperature is very slow when starting up, for several minutes, and then the temperature rises sharply. If you don't pay attention, you will burn everything. Such as power amplifier, CPU, circuit board, etc. Although it also has temperature detection, it seems that it is only used for over temperature protection, and does not really adjust the temperature value. It is suggested that we do not often pay for the machine in order to save money.
Standard type electric heat guns
The scale of this hot air gun is really used to adjust the temperature. It can be reached in tens of seconds when starting up, and the temperature will not rise in a straight line. It can be adjusted in a small range, and the air volume is relatively stable. It is suitable for repairing mobile phones. I use this air gun very well. For example, more than 90% of the CPU of 3508 will not burn out.
Digital temperature display type Mini heat gun FBelec Brand
This is basically the same as the second performance, that is, there are multiple digital temperature displays, some of which are very accurate and accurate. However, some display temperature is inaccurate, which is easy to produce false perception. In addition, according to the different manufacturers and production sooner or later, the products that were long ago may not be practical.
In addition, the actual use temperature measured by the digital thermometer is: (small head air nozzle) 350-400 degrees at the air outlet, about 300-350 degrees at one centimeter and 260-300 degrees at two centimetres. It can be tested with a digital multimeter with thermometer.
At the same time, some machines are equipped with power or other voltage and current indicating dials. Some parts can be replaced.
If a hot-air gun without digital temperature is used, it can be estimated by blowing a piece of paper at 3cm. If the paper will not turn black soon, it is appropriate to turn yellow slowly.
High temperature type
The high temperature hot air gun can be used only when the temperature can reach 800 ℃ or even 900 ℃ and must be fixed on the equipment and connected with compressed air or high-pressure air source.
The high-temperature hot air gun is generally equipped with one or two temperature sensors for temperature control, and also equipped with an anti dry burning device to prevent the heating wire from overheating and burning out due to lack of air.
